We are on our second RV and find that the dump valve push/pull rods have failed, either by bending or by the plastic T-handle breaking. My solution was to use a 1/2-inch stainless-steel tube with a 3/8-inch inside diameter and make my own T-handles from steel.
The original threaded bushing that attaches to the valve itself fits perfectly in the 1/2-inch tube. I drilled holes in each end to attach a cotter pin through the original threaded bushing and the custom steel T-handle that I made for the pulling end of the dump valve. When threading the bushing end back to the valve, I used blue Loctite. I painted the T-handles green because in the state of Indiana construction sites use green as the locating color for sanitation, plus it’s easier to see when taking a first glance under the RV.
These work so much better and do not bend or break.
